Federer currently comes into the net only if it is unimportant points/situations.
Like when he is leading 40-15, or leading a set by 4-1 score etc.
And he fails lots of them, almost look like he is practicing them.
When pressure mounts or he is trailing in score, he still stays at the baseline more or less.
That's always his strategy. He is not ready to use net at crucial points.
Who knows? He might be practicing it until he gets confident with it...
